Dubious but worth recording: A tract dated 1622 reports a vast war of starlings over Cork, Ireland, Oct. 12-14, 1621. Armies of birds had reportedly converged from the east and west some four or five days before, and on Oct. 12 “they forthwith, at one Instant, took Wing, and so mounting up into the Skies, encountered one another with such a terrible Shock, as the Sound amazed the whole City and the Beholders,” until “there fell down in the City, and into the Rivers, Multitudes of Starlings or Stares, some with Wings broken, some with Legs and Necks broken, some with Eyes picked out, some their Bills thrust into the Breast and Sides of their Adversaries, on so strage [sic] a Manner, that it were incredible, except it were confirmed by Letters of Credit, and by Eye-Witnesses with that Assurance which is without all Exception.”
The birds adjourned, for some reason, on Sunday, though visitors from Suffolk reported seeing a similar war over remote woods there. On Monday the fight resumed over Cork, and this time the dead included a kite, a raven, and a crow.
I can’t find the original pamphlet, but it’s referenced by Johns Hopkins (1905), the London Library (1888), the New York State Library (1882), and the Bodleian Library (1860), among others. Starlings do have a colorful history — see Oops and Fragments of Night.
